lIMPROVEMENT IN LOCKS FOR FIRE-ARMS.

Specification forming part of Letters Patent No. 220,785, dated October 21, 1879 5 application fil-ed February 17, 1879,

To all whom 'it may concern.-

Be it known that I, ALBRECHT EDWARD BARTHE'L, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Revolving Fire- Arms, of which the following is a specification.

My invention relates to a hammerless selfcockin g and rebounding tire-arm, the improvements being applicable to shot-guns, rifles, or revolvers, either single-loaders or`1nagazinearms.

The object of my invention is to simplify the construction, to dispense with the' usual projectingl parts, and to obtain rapidity of firing; and the invention consists in certain novel features of construction, set forth hereinafter, and shown in the accompanying drawings, whereini y i Figure 1 is a section lengthwise of the stock, showingV the rin'g mechanism, in elevation and in its normal position. Fig. 2 is a similar view with the firing-pin retracted. Figs. 3, .4, 5, and 6 are detail views of the parts of the firing mechanism. Figs. 7 and S are, respectively, a longitudinal section and elevation of the gun in modied'form. Fig. 9 is a sectional plan on line .r a of Fig. 7 t 4 Similar letters of reference indicate corresponding parts.

Referring to Figs. 1 and 2, B is the stock, and G the revolving barrel-piece, of a shotgun or rifle. A is a fixed breechplate or block behind the barrels.

The firing mechanism is containedwithin a cavity in stock B, behind plate A, and the lower side of the cavity is closed by the trigger-plate s, that is formed with a tri ggerguard, o, as usual.

t The tiring-pin a is tted to slide in the breech-cavity, and is projected by a spring, e. "A trigger-lever, b, is fulcrumed at t', and is formed at its lower end as a trigger, r. This lever bis inortised at a (see Fig. 5) for the iring-pin c to pass through it, and also passes at each side of the magazine-tube h. The rin g-p'in a is mortised to receive a pawl or dog, c, that is hung loosely on cross-pin d, so that Around tube 71. is a spiral spring, f, that i bears upon lever b, and returns the lever Ito position after tiring.

4The parts described operate as follows By drawing the trigger and lever b back, the shoulder b of lever b acts upon dog c, and the dog not being capable of further downward movement, the pin a is forced back to the po-v sition shown in Fig. 2, and its spring e is compressed. v In the iirst named position, the point of contact between b and c is in advance of the fulcrlun t', and as lever b moves the shoulder b drops downward until it clears c,- and permits pin a to spring forward to re the cartridge.- Upon releasing lever b after firing, it is thrown forward by its spring f, the shoulder b' raises dog c, which latter drops to place as soon as the shoulder has passed'. The pin a is caused to rebound from contact with the cartridge by means of the fingers l l, formed on lever b (see Figs. 1, 5, and 6) and projecting upon pin a. The pin a has curvedside lugs or projections, n, (seeFigs. 1, 3, .and 4,) that are acted upon by iin gers l on the return movement of lever b, and-the pin a, thereby `forced back slightly.

In Figs. 7, 8, and 9 a modification is shown, whereby I dispense with the projecting trigger-guard o. In this construction the tube f1. is not used,the trigger 1' is within the breechcavity, andV access is had to the trigger through mechanism having but few parts. lThe sides b-, and the springs ef, substantially as described and shown,.and for the purposes set forth.

2. The combination of the firing-piu a, provided with lugs n, and trigger-1ever b, having fingers l, whereby a retraction of the firingpin is caused by the rei-urn movement; of the lever, Vas set forth.
